But when it's so easy to intimidate a police woman merely by being 5 foot 11 inches tall and taking her photo - then I think it's time to give up - the terrorists have won already. Obviously she'd simply die of fright if ever a taller man - with a beard were to go "Boo!" at her.

Of course - there's another law altogether for the police - whenever they feel like it they can take pictures of whoever they like, whenever they like: Police photograph anti-airport campaigners talking to MP.* Yes, you read that right - don't you dare go and talk to your MP - lest you want the police to suspect you of being one of those evil terrorists and put you on their lists.
